Intermittent gastric outlet obstruction and mild acute pancreatitis caused by large gastric pedunculated polyp. A video case

Abstract Text A 75 y.o man, admitted for recurrent post-prandial vomit for two weeks. CT scan showed a 25 mm solid polyp in second duodenum,and pancreatic head enlargement. Blood test increased amylase and lipase consistent with acute pancreatitis. MRCP excluded biliary stones. Gastroscopy showed a pedunculated polyp with long stalk in the antrum and a 25 mm head prolapsed in duodenal bulb, causing an intermittent ball valve obstruction. Polyp resection solved patient symptoms. Gastric polyps can rarely protrude through the pylorus and causing progressive gastric outlet obstruction, even rarer is ampulla of Vater compression [1] [2].
